22 Mounting and wiring the DUT on the socket module You can mount and wire the DUTs as described in the following. Non-Kelvin connections Connect the pin plug to pin plug cables between the Output terminals on the U2941A and the desired terminals on the socket module. Kelvin connections Connect a pin plug to pin plug cable between the Output terminal on the U2941A and the desired terminal on the socket module, and then connect a pin plug to miniature clip cable between the Sense terminal and DUT lead. The U2941A enables usage of the Kelvin connections for a maximum of three U2722A channels. The following figure shows an example of the Kelvin connection for channel 1. Connected to the O terminal of channel 1 Connected to the S+ terminal of channel 1 Connected to the O+ terminal of channel 1 Connected to the S terminal of channel 1 DUT 14 U2941A Operating Guide

23 You may also connect an additional pin plug to pin plug cable between the Sense terminal and the hole of the pin plug connected to the terminal as shown in the following figure. Connected to the S+ terminal Connected to the O terminal Connected to the O+ terminal Connected to the S terminal U2941A Operating Guide 15

24 Connections for a uniquely shaped device If there is no suitable socket module for a uniquely shaped DUT, you can connect the device by using the assembly Teflon plate or universal socket module as described in the following. Assembly Teflon plate Connect the terminals directly to the DUT on the assembly Teflon plate using the pin plug to miniature clip connection cables, as shown in the following figure. Ensure that the DUT is placed on the assembly Teflon plate. Connected to the O terminal Connected to the O+ terminal DUT Assembly Teflon plate 16 U2941A Operating Guide

25 Universal socket module The provided pitch sizes (0.1 inch, inch, and 0.05 inch) offer you the flexibility to mount your DUT on the U2941A. You may either solder the DUT directly or insert an IC holder on the universal socket module. Open the casing of the socket module by removing the screws and use a wire to connect the DUT lead or IC holder lead to the jumper pin which is inserted on the socket module. The jumper pins connection at the bottom layer of the printed circuit board (PCB) is shown in the Bottom view figure. The other end of the jumper pins at the top layer of the PCB allows you to connect the terminals to the jumper pins using the pin plug to miniature clip cables as shown in the Top view figure.

29 Maintenance To maintain high performance, the U2941A must be kept clean. Oil, perspiration, hair, dust, and dirt will degrade board insulation, which increases leakage current and decreases measurement accuracy. Agilent recommends the following cleaning procedures. Chassis, lid, inner plate, and socket modules 1 Ensure that voltage or current is not applied to the U2941A. 2 Remove all connection cables from the U2941A. 3 Using lint- free paper, gently wipe the chassis, lid, inner plate, and socket module. For any area that will not come clean, dip the lint- free paper into alcohol and wipe the area gently. Connection cables 1 Ensure that voltage or current is not applied to the U2941A. 2 Remove the connection cables from the U2941A. 3 Dip lint- free paper into alcohol and gently wipe the metal contacts of the connection cables.
